Neurotrauma
Neurotrauma refers to critical injuries to the brain, skull, spinal cord, and surrounding tissues, usually resulting from sudden physical impact or mechanical force. It encompasses Traumatic Brain Injury (TBI) and Traumatic Spinal Cord Injury (tSCI), both of which require rapid emergency assessment and surgical or medical stabilization to prevent secondary neural damage.
Core Neurotrauma Conditions
Epidural Hematoma (EDH): Bleeding between the inner surface of the skull and the dura mater, usually caused by arterial tears (e.g., middle meningeal artery) following skull fractures.
Subdural Hematoma (SDH): Bleeding between the dura mater and arachnoid membrane, typically resulting from ruptured bridging veins following high-impact trauma or acceleration-deceleration forces.
Traumatic Subarachnoid Hemorrhage (tSAH): Bleeding within the subarachnoid space due to microvascular disruption from severe head impact.
Intracerebral Contusion & Hemorrhage: Direct bruising or tearing of brain parenchyma causing localized edema, elevated intracranial pressure (ICP), and tissue necrosis.
Skull Fractures: Linear, depressed, or basilar skull fractures that risk tearing the dura mater, causing cerebrospinal fluid (CSF) leaks, or direct bone displacement into brain tissue.
Traumatic Spinal Cord Injury (tSCI): Fractures or dislocations of the vertebral column leading to compression, transection, or ischemia of the spinal cord (e.g., cervical, thoracic, or lumbar spine fractures).
Primary Surgical & Medical Interventions
| Category | Typical Clinical Indication | Primary Intervention / Goal |
| Emergent Decompression | Decompressing severe acute SDH/EDH or malignant brain edema | Decompressive Craniectomy or Craniotomy: Removal of bone flap to evacuate clot and relieve critical intracranial pressure. |
| Depressed Fracture Repair | Bone fragments driven inward toward brain tissue | Skull Fracture Elevation & Reconstruction: Surgical lifting and stabilization of bone fragments to prevent brain laceration and infection. |
| Spinal Decompression & Fusion | Vertebral column fracture, dislocation, or spinal cord compression | Spinal Reduction & Instrumentation: Realignment of vertebrae, pedicle screw fixation, and laminectomy to relieve cord pressure. |
| ICP & Hemodynamic Management | Refractory intracranial hypertension without localized resectable mass | External Ventricular Drain (EVD): Placement of an EVD or parenchymal catheter for continuous ICP monitoring and therapeutic CSF drainage. |
Emergency Neurotrauma Management Workflow
Rapid Triage & Primary Survey
ATLS protocol implementation, airway/breathing stabilization, Glasgow Coma Scale (GCS) assessment, and cervical spine immobilization
↓
Emergent Diagnostic Imaging
Non-contrast CT scan of head/cervical spine to detect hematomas, midline shift, skull fractures, or spinal column injury
↓
Surgical vs. ICU Intervention
Immediate craniotomy/craniectomy for mass-effect hematomas, or EVD insertion and hyperosmolar therapy (mannitol/hypertonic saline) for elevated ICP
↓
Neuro-Intensive Care Unit (Neuro-ICU) Stabilization
Continuous monitoring of cerebral perfusion pressure (CPP), blood pressure optimization, seizure prophylaxis, and secondary brain injury prevention
